50 is formed with the transversely extendin out The present invention relates to improvements in rail ties and has for its principal. ob-. ject to provide a tie that includes a'concrete base, and aspring steel rail supporting plate arranged on the concrete base in spaced rela tion thereto, meansbeing provided forposi-v tively anchoring the rails on the'upper face of i the steel plate so that spreading of the rails will be prevented. v v I Another important object of the invention to provide a rail tie of the above mentioned character which is simple in construction, in-

expensive, strong and durable and further well adapted to the purpose for which itis designed. y

Other objects and advantages of the inventionwill become apparent from the following" description when takenin connection with the accompanying drawing, I i In the accompanying drawing wherein like reference characters indicate corresponding parts throughout thesa'rnez' i 1 Figure 1 is a side elevation of the rail tie ,embodyingmy invention showing the manner in which a pair ofrails are supportedand see cured on the u er face of the s ring steel plate.

and c Figure 3 is a 'verticalsecti'on taken on the line 33 of Figure 1 for inoreclearly showing the inverted U-shaped member. 1 v

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the concrete base 'of'the tie'that is of substantially rectangularshape. A spring steel plate 2 of the same dimensionsas the concrete base E1 is adapted for. disposition on top of the base in spaced relationthereto, and to this endya pair of rollers or pins 3 eXtend transversely between-the inner opposed faces of the base and plate; A washer-4: is disposed on each end of each pin for disposition against the adjacent side of the concrete base and the 5 steel plate 2, and a cotter pin 5 extends through an opening formed in the outer ends of each pin to properly retain the pins against displacement; i U The upper face of'the spring steel plate 2 out portion 6, 6 adjacent the respective ends thereof to receive the base of the rails '7. The

intermediate portion'of' the top face'offthe steel plate 2isfurther formed with a transverse cut out portion toreceive the crown 8 Figure 2 is a planview partly in'section of a substantially inverted u shaped member;

the armsthereoilt being disposed downwardly y I on opposite sides of the steel plate tHlCl'liIllGCOIl'va crete base as shown at 9 in Figure 3. The. free end'of each arm is bent laterally as at 10, and thence upwardly as at 11 to form the opposed 1 saddles 12. The purpose of'these saddles Will be hereinafter more fully described. i f i The rail securing means will: now be specifically described. A sleeve 13 is disposed withinla transverse opening formedin the" p concrete base l'directly below each rail 7 and extending through each sleeveis the elongated, pin 14, the ends of the each pin projecting be yond the respective sides of the: concrete-base. A pair of bars 15 are disposed on opposite sidesof the concrete base in diagonally'op posed relation, and each of thesebars is bent intermediate its ends to form an upwardly di-.-

rected portion 16, the free end of which is-dis-J posed inwardly as shown at 17 toengagewith the base of the adjacent rail. These bars have theirv bightportions 18 disposed around the respective pins 14 at the outer'ends thereof and iawasher 19 is placed overthe respective pins at one end thereof for engagement with the bight portions of the bars; cotter vpin 20 extends transversely -througl i an opening formed in each end of" each pin so that's aid bars will be vprevented from sliding off of the ends of therespective transverselydisposed I pins;

- Cooperating with the bars 15 are additional v bars 21 the samebeing disposed on opposite sides of the tie and in diagonallyopposed relat-ion. Theouter end'portion of each bar21 is curved as at 22' to provide a pin engaging:

portion, and the end portion of ea'ch bar ex tends upwardly at an incline as at 23, andthe laterally disposed foot 24; is formed on the up portion of the respective rails at the inner edge thereof, as indicated very clearly in Fig' nres 1 and 2 of the drawing.

The inner encliportion ofeach" ofthebars 21 is adapted for rest upon the respective saddles 12; and-as is shown very clearly in per end thereof for engagement with the base Figures 1 and 2, the inner extremity of each bar 21 terminates in a threadedcyli'ndrioal portion25'. r i 'g A turn buckle 26 is swivelly connected at one end to the'inner end of each'ba-rlfit'while the other en dis formedwit-h a threaded opening to receive the threaded inner-end of the respective bar 21 and manifestly by actuating the turn buckle, the 'bars1 15 and 21'on ea'ch side of thetie may be adjusted toward or away from each other,

Additional washers 19 are arranged on the other ends of the transverse. ins around which the curved portions 22 0 the bars 21 extend and additional cotter pins 20 extend through these particular ends of the pins to retain the washers and the bar 21 in position.

Normally the parts are arranged as shown in Figure 1, and the spring steel plate that supports the rails '7 will be properly spaced with respect to the concrete base 1, and the hooked upper ends of the bars will firmly engage with the inner and outer edge portions of thebaseflanges of the rails to positively secure the rails on the spring steel plates.

Under certain circumstances, where v a heavy load is laced on one of the rails, this particular end of the steel plate will flex downwardly, but the saddle carrying member will cooperate with the inner connected bars to all times maintain the hooks or feet-17 and 24 in engagementwith theb'ase flanges of the" rails so that said rails cannot be dis placed from their recesses seats 6 formed in the upper face of the steel plate, and when the load is taken oil of the flexed end of the spring steel plate, said spring steel plate will return'to its'initialhorizontal position. It is of course understood that when the endof the bar-2 is depressed, the middle portion with the saddle is raised to avoid loosening'of the ba-rsobout the pins 14.

It will thus be seen from the foregoing de-' scription that I have provided arail tie that. willibe strong and durable, and at the same time prevent spreading of the rails.

Furthermore, the tie can be readily and easily assembled or disassembled whenever necessary.

While I have shown the preferred embodiment of my invention, it is to be understood that minor changes in the size, shape and arrangement of parts may be resortedto without departing from the spirit of the invention, or the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a rail tie, a plastic base, a spring steel plate for disposition on top of the plastic base in spaced relation thereto. rails arranged transversely across the upper face of the steel plate, means for securing the rails against movement independently of the steel plate, said means including a substantially inverted U-shapedmember arranged over the" intermediateportion of the steel plate and the base, saddles formed on the free ends. of the arms of the inverted U-shaped member, pins pmjecting transversely through the concrete base beneath the respective rails, rods arranged on opposite sides of the plastic base, the outer end portions of the'rods being bent fbr disposition around the respective ends engaging feet formed on the upper end of the upwardly bent outer ends of the rods, the intermediate portions of the rods being adapted for rest within the respective saddles.

2. In a rail tie, a concrete base, a spring steel plate for disposition above the concrete base, pins extending" transversely between the opposed faces of the concrete base and the spring steel plate to space said plate with re spect to the base, a pair of rails arranged transversely across the upper face of the spring steel plate adjacent the respective ends thereof, a substantially inverted U-shaped member straddling the intermediate portion of the spring' steel plate, saddles formed on the free ends of the arms of said invertedU- shaped member, a pair of bars arranged on each side of the concrete base, means for adj ustably' securing the inner ends of each pair of bars together, the outer ends of the bars being bent upwardly for disposition ad'acent the sides of the spring steel plate, pins extending transversely through the concrete base beneath the respective rails, the bight portions of the bars being disposed around the respective ends of the pins, base flange engaging feet formed on the upper ends of the upwardly disposed portions of said bars, said saddles adapted to support the adjacent portions of the respective bars.

3. In a rail tie, a coneretebase,

a spring steel plate for disposition above the concrete base, pins extending transversely between the opposed faces of the concrete base and the spring steel plate to space said plate with re-' speet to the base, apair of rails arranged transversely across the upper face of the spring steel plate adjacent-the respectivcends thereof, a substantially inverted U-shaped member straddling the intermediate portion of the spring steel plate, saddles formed on the free ends of the arms of said inverted U- shaped member, a pair of barsarranged on each side of the concrete base, means-for adjustably securing the inner ends of each pairof bars together, the outer endsof the bars being bent upwardly for disposition adjacent the sides ofthe spring steel plate, pins extending transversely through the concretebase beneath the respective rails, the bightpon tions of the bars being disposed around the respective ends of the pins, base flange engaging feet formed on the upper ends of the upwardly disposed portions of said bars, said saddles adapted to support the adjacent portions of the respective bars. the aforemem 'tioned adjusting means including a turn buckle swivelly connectedto the inner end of one bar on each side of the tie,the inner end of the complementary bar being formed with a threaded portion for threaded engagement with the turn buckle.
